I have an InnoDB database table with more than 2 million rows. I am running efficienty indexed queries to reduce server load, but site becomes slower day by day.
I ran Mysqltuner.pl to identify any problems with server configuration. I don't have any prior experience with MySQL tweaking. Please suggest me the correct configuration on the basis of below info.
